PENCIL ATTACHMENT FOR SECTIONAL RULES.

Application led September 30, 1918. Serial No. 123,03@

To all 'whom t may concern.'

HERMAN HAUPTMAN, a subject of the Emperor of Austria, residing atPittsburgh; county of Allegheny, and State of Pennsylvania, haveinvented certain new and useful Improvements in Pencil Attachments forSectional Rules, of which the following is a specification.

This invention relates to a pencil attachment for sectional rules,.andhas for its object to provide means secured to one of the sections ofthe rule for connecting a lpencil therewith, said means not impairing inany manner the extending or the folding of the rule.

Further objects of the invention `are to provide a pencil attachment forrules which is simple in its construction and arrangement, strong,durable, eiicient and convenient in its use, and inexpensive tomanufacture.

With the foregoing and other objects in view the invention consists ofthe novel con-y struction, combination and arrangement of parts ashereinafter more specifically described 'and illustrated in theaccompanying drawing, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claim hereuntoappended.

In the drawings wherein like reference characters denote ,correspondingparts throughout the several views:-

Figure "1 is an elevation of a sectional rule showing the adaptationtherewith of a pencil attachment in accordance with this invention andfurther showing the attachment secured to two of the sections of therule.

Fig. 2 is a plan of the blank from which the'- attachment is Jformed.

Referring to Figs. 1 and 2 of the drawings 1, 2, 3 and 4 denote thesections of` a rule and connected to each of the sections l and 4, whichare the outer sections of the rule, is a pencil attachment in accordancewith this invention. Each of the sections 1 and 4 is provided with twopairs of longitudinally extending spaced slots and the slots of one pairare indicated at 5 and the Y slots oir' the other pair at 6.

The blank from which the pencil attachment is jtormed consists of alongitudinally extending body 7 formed of a narrow strip:

of metal, and which has projecting laterally, at points intermediate theends t ereof, two pairs-ofbendable wings, the wings of one pair areindicated at 8 and the wings of the other pair are indicated at 9. 4

Formed integral with the body 7, and spaced from the wings 8 and 9, aretwo pairs of bendable projections, and the projections of one pair areindicated at 10 and the projections of the other pair at 11. The wings8, 9 are bent outwardly and "curved to provlde clamps, the clamps formedby the wings 8 are indicated at 12, and the clamps formed by the wings 9are indicated at 13. The projections 10 and 11 are bent inwardly toprovide securing members and the members formed by the projections 10are indicated at 14 and those formed by the projections 1l are indicatedat 15.

`When the attachment is connected with the section of a rule, theprojections 10, 11 are passed through the slots 5, 6, of the rulesection and then bent upon the inner face of the rule section wherebythe attachment is detachably connected with the section, as illustratedin Fig. 1.

The body 7 of the attachment is such as not to interfere with thegraduations of the rulesections and the material Jfrom Vwhich theattachment is made is so thin as not to interfere to any great extentwith the rule sections .when one or moresections are'connected to therule.

What I claim is ;--V

A pencil attachment for rules comprising an elongated flat body portionprovided near each end with a pair of oppositely disposed projectionscapable of being bent outwardly to provide clamping means, said bodyportion further provided at each end with a-pair of laterally projectingoppositely disposed lugs capable of being bent inwardly to extendthrough a rule for securing said body portion therewith the lugs at theends of the body portion spaced from the other lugs.

In testimony whereof I aiix my signature in the presence of twowitnesses.

HERMAN HAUPTMAN.
